Abstract
The invention relates to a method for drawing or penetrating a rotor of a power generator for a nuclear power plant. The method includes looping a steel wire rope on a fixed pulley, connecting two ends of the steel wire rope to a rotor exterior end drawing tool and a crane respectively, and finally completing drawing or penetrating of the rotor by hoisting of the crane. Compared with the prior art, the method has the advantages that labor is saved, labor intensity is reduced, work efficiency is improved, the rotor runs stably, safely and reliably, and can be penetrated without limitation of operation of a low-pressure cylinder of a turbine, the method has wide application range and the like.
Description
Technical field
The present invention relates to a kind of method that extracts rotor, especially relate to the method that a kind of nuclear power house alternator is taken out penetrate rotor.
Background technology
Develop rapidly along with electric utility, the service work of Generator Set is day by day heavy, and the difficult point of generator overhaul and major tasks are to take out to wear generator amature, and the weight of heavy-duty generator rotor weighs 50 to more than 100 tons, technological requirement is high, and difficulty of construction is large.In recent years, high-rating generator is taken out rotor and is adopted slide plate to add the method that slide block or slide plate add dolly more, and the method is safe and reliable and reach its maturity, but general chain block with two 5 tons draws during site operation, labour intensity is large, and it is uneven steady that rotor is advanced, and wholely takes out that to wear the course of work slow.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists and save manpower, reduce the widely nuclear power house alternator method of taking out penetrate rotor of labour intensity, the scope of application.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of nuclear power house alternator is taken out the method for penetrate rotor, it is characterized in that, the method is by being located at steel wire loop on the fixed pulley, and the steel wire rope two ends are connected to rotor encourage in end drafting tool and the driving, finishes the extraction of rotor or penetrates by the lifting of driving.
The method that extracts rotor specifically may further comprise the steps:
(1) in the center of encouraging the end body away from generator a fixed pulley is installed;
(2) encouraging the end drafting tool at rotor installs steel wire rope and is sheathed on the fixed pulley after the steel wire rope solderless wrapped connection is on rotor again;
(3) steel wire rope by the fixed pulley rear-mounted the driving little colluding on;
(4) promote slowly driving, move outside the lifting steadily of rotor along with driving, namely finish the extraction of rotor.
The method that penetrates rotor specifically may further comprise the steps:
(1) in the center of encouraging the end body away from generator a fixed pulley is installed;
(2) at the former exciter of encouraging end body place near generator or the center on brush holder basis another fixed pulley is installed;
(3) encourage the end drafting tool at rotor steel wire rope be installed, this steel wire rope solderless wrapped connection on rotor after first and the fixed pulley on exciter or the brush holder basis link to each other with the fixed pulley of distant place again after being connected;
(4) with steel wire rope by distant place fixed pulley rear-mounted the driving little colluding on;
(5) promote slowly driving, rotor is namely finished penetrating of rotor along with the lifting of driving steadily pushes in the generator unit stator thorax.
Compared with prior art, the present invention has the following advantages:
(1) saves manpower, solve the nervous problem of human resources;
(2) reduce labour intensity, increase work efficiency;
(3) rotor is advanced steadily, and is safe and reliable;
(4) be not subjected to the restriction of steam turbine low-pressure cylinder working during penetrate rotor;
(5) scope of application is extensive, can generally be used for the maintenance of adopting the slide plate method to take out the heavy-duty generator of penetrate rotor.
